Please run the following command in a terminal:

SFC has worked numerous times for me, usually for botched updates. Haven’t used it in a long time after leaving tech support
I’ve tried using SFC multiple times and had it work zero times. One time after SFC failed to find anything wrong, I ended up fixing the machine by replacing the system file with a copy from a working machine.
